This is a wonderful picture to color because a variety of colors can be used here. The theme here should be Christmas as the picture is related to Christmas. So when coloring this picture it is advised to keep Christmas colors in mind like the red, green, and brown. Starting with Santa his hat and cloths should be colored red while his beard is kept white and face can be of light brown shade. The reindeer can be colored brown and the top of his head can be a different shade of brown. The tie on his face should be colored red as that’s the true Christmas color. The North Pole poster can be colored of any preferred pretty color where the presents should be golden or green. Now only the background is left that can be a light shade of blue to make everything else stand out.
